A prop firm (proprietary trading firm) is a company that allocates its own capital to independent traders, who keep a share of the profits after passing a structured evaluation. Unlike a brokerage, a prop firm takes on the financial risk so traders can operate at scale without risking personal savings — though that access comes with strict rules around drawdown, consistency, and trade sizing.
Key Takeaways
- Evaluation-based prop firms require passing a two-phase challenge — typically a 10% profit target in Phase 1 and 5% in Phase 2 — while staying within daily (5%) and total (10%) drawdown limits.
- Profit splits range from 70/30 at instant-funding firms to 80–90% for the trader at evaluation-based firms; the higher the split, the stricter the rules.
- Most retail prop firm “funded” accounts are simulated — profits are paid from the firm’s treasury, and the business model depends heavily on the 80–95% of traders who fail challenges and forfeit their fees.
How a Prop Firm Works
The modern retail prop firm model uses a paid evaluation, or “challenge,” to identify consistently profitable traders before allocating capital. The two-phase structure used by FTMO — the firm that popularized this model around 2015 — has become the industry standard:
- Phase 1: Hit a 10% profit target within 30 days without breaching a 5% daily drawdown or 10% total drawdown limit.
- Phase 2: Hit a 5% target under the same drawdown rules within 30 days.
- Funded stage: Trade a live (or simulated-live) account at an agreed profit split.
Challenge fees scale with account size. An FTMO $100,000 account costs $540; a $25,000 account costs $167. If the trader passes, the fee is typically refunded in the first payout.
Beyond hitting the profit target, traders must satisfy consistency rules that trip up many who otherwise meet the numbers. Common restrictions include:
- No single trade may account for more than 30–50% of total profits.
- Trading is prohibited during a defined window around major news releases.
- Only instruments on the firm’s approved whitelist may be traded.
Violating any of these can terminate a funded account even if the profit target and drawdown limits are intact.
Practical Example
A trader purchases an FTMO $25,000 challenge for $167. Phase 1 requirements: earn $2,500 (10%) within 30 days, with a maximum single-day loss of $1,250 (5%) and a maximum total drawdown of $2,500 (10%).
Trading EUR/USD with 0.5 lot sizes — where each 10-pip move equals $50 — the trader risks $125 per trade (0.5% of account) at a 2:1 reward-to-risk ratio. After 18 trading days, the account is up $2,600. Phase 2 requires $1,250 (5%) under the same drawdown rules over 30 days. The trader passes and receives a $25,000 funded account.
In the first funded month, the trader nets $3,200. At an 80/20 split, the payout is $2,560 — covering the $167 challenge fee with $2,393 in net profit remaining.
A prop firm gives traders access to company capital in exchange for a share of profits, usually 70 to 90 percent to the trader. Access requires passing a paid evaluation with profit targets and strict daily loss limits before any real funding is granted.
The Business Model Reality
The prop firm industry bifurcates into two models:
- Evaluation-based firms (FTMO, TopStep, Apex Trader Funding): charge a challenge fee, offer 80–90% splits, enforce strict rules. TopStep charges $150/month for a $150,000 simulated futures account on CME products (ES, NQ, CL, GC) with a 90% split after the first $10,000 withdrawn.
- Instant funding firms: no challenge required, lower splits around 70/30, often fewer rules.
Industry estimates place the challenge failure rate at 80–95%. This is not incidental — it is the revenue engine. Profits paid to successful traders come from the firm’s treasury, subsidized by the majority who forfeit challenge fees.
The regulatory risk is real. In August 2023, the CFTC and CIRO filed charges against MyForexFunds, freezing approximately $310 million in assets and leaving thousands of traders unable to access payouts. The case highlighted that most retail prop firm “funded” accounts are paper-trading environments, not live brokerage accounts, placing them outside standard investor protections.
Before paying a challenge fee, traders should verify a firm’s payout history, jurisdiction, and whether funded accounts involve real capital or simulation.
Common Mistakes
- Targeting the profit number, not the process. Traders who overtrade in the final days to hit the target often breach the daily drawdown limit after already passing the consistency threshold.
- Ignoring the single-trade profit cap. One outsized winning trade — say, 60% of total profits from a single position — can disqualify an otherwise passing challenge.
- Trading restricted instruments or news events. Many challenges prohibit trading 2–5 minutes before and after high-impact news. Brokers log entry timestamps; violations are enforced retroactively.
- Choosing a firm by split percentage alone. A 90% split from an instant-funding firm with no challenge means lower capital allocation and higher risk of arbitrary account termination than a structured evaluation firm.
How JournalPlus Tracks Prop Firm Metrics
JournalPlus logs every trade with timestamps, position size, and P&L, making it straightforward to verify compliance with consistency rules before submitting for a payout review. The analytics dashboard surfaces win rate, average risk-per-trade, and max drawdown — the exact KPIs prop firms evaluate — so traders can identify weaknesses during the challenge phase rather than after a breach. Traders preparing for a funded account evaluation can use JournalPlus to simulate challenge conditions against their own historical trade data.
